virt-viewer/src/virt-viewer-window.c
Jonathon Jongsma 2ec0387adc Disconnect fullscreen map-event handler when leaving fullscreen 
When we enter fullscreen mode before the window is shown, we set up a signal
handler to enter fullscreen mode when the window is mapped.  If we then leave
fullscreen mode before the window is mapped, we don't disconnect this handler,
so it will still enter fullscreen mode when it is shown.
